Study Background

Women’s College Hospital, Sunnybrook Health Sciences and the Centre for Addiction and Mental Health are conducting a research study investigating a non-drug alternative, transcranial direct current stimulation (tDCS), for treating depression in pregnancy.

Depression in pregnancy is common  – it affects about 1 in 10 pregnant people. Current options for treating depression are not ideal for everyone:

  • Talk therapy  – Can take weeks to months to improve symptoms or might not work on its own
  • Medication –  Can work quickly, but people do not always wish to take them in pregnancy


Transcranial direct current stimulation (tDCS) is a non-drug treatment for depression.

  • It is a small and easy-to-use device that patients can self-apply at home
  • Over 3 weeks of treatment, it has been shown to improve depression symptoms in a lasting way
  • In this research study:
    • You will be able to self-apply the treatment at-home, and a research staff member will be with you over secure video-visit during each treatment.
    • You will receive follow-up for the rest of your pregnancy and until 1 year postpartum.
    • Tokens of appreciation are given for completing research surveys (up to $190 total in the form of gift cards)
